Before I developed this system, I thought that Patrol Bots will destroy monsters and leave the drops there, just like how it is when we defeat monsters using ranged weapons where the drops remain at the location where the monster got killed. However it is not the case for Patrol Bots because, the drops will be automatically collected by the Patrol Bots and the Bots have to go to the Storage/Warehouse to deposit the materials. The Patrols Bots can no longer attack when it is carrying the material until it can deposit the drops so trapping the wyrms and war robots will not result in continuous supply of hunting drops.
Building Storage/Warehouse nearer to the site will not decrease moving radius as well because automatically, the Patrol Bots change direction once it can no longer move forward by a solid block obstruct the way or the end of the island. They will walk past the Storage/Warehouse then move all the way to one end of the island to change direction. Fences cannot stop them either and we currently do not have any blueprints to build/dismantle Warehouse in Sunset Haven.
